Abstract

The decorative panel includes a substrate and a top layer. The substrate has at least one of polyvinyl chloride layer. The top layer includes a decorative textile layer providing the surface of the decorative panel. The top layer is laminated onto the substrate by thermal bonding of the top layer onto the substrate; or by a polyvinyl chloride based adhesive layer. The substrate is provided at a first pair of opposite edges with coupling parts, substantially in the form of male coupling parts and female coupling parts, for coupling two such panels to each other at their first pair of opposite edges. The coupling parts are provided with locking means which effects a locking in coupled condition of two such panels in the direction perpendicular to the surface of the coupled panels and/or into the direction perpendicular to the respective edges in the plane of the panels.
